As it turns out TARGET_ARCH and XEN_ARCH do differ a bit. x86-64 versus x86_64. While we could use TARGET_ARCH as an override and be correct .. I'm worried about clarity in the recipes if I start mixing the two architecture variables. I prefer the overrides mechanism as well, but for now, I'll go with the anonymous python snippet.
